A bag, having a top opening and a draw cord arrangement adapted to close the top opening, is provided with a dust ruffle, which is secured inside the bag and extends upward and through the top opening. By this arrangement, the dust ruffle shirrs the top opening when the bag is closed, thereby inhibiting the entry of particulate matter. The dust ruffle is provided with a pair of holes, so that a plurality of bags can be formed into a bag-pack for use on automatic filling equipment by stacking the bags, with the dust ruffle holes aligned, and inserting the rods of a bag-holder into the stack of bags to retain them as a unit. In one embodiment, the bag-holder is inserted from the rear of the stack of bags to form a bag-pack. The bag-pack is then loaded onto an automatic filling machine provided with a pair of hollow, parallel, generally horizontal rails by inserting the rails into the dust ruffle holes and allowing the bag-holder rods to enter the rails. By this arrangement, the stack of bags is supported in a generally vertical position and the bags are filled and removed from the front of the stack, with the stack being advanced along the rails as bags are filled. When the supply of bags on the rails is low, additional bags are added without stopping the machine by removing the bag-holder from the rails and loading a new bag-pack behind the bags remaining on the rails.
